註釋The Quesnel Highlands study area lies north of Quesnel Lake and includes Wells Gray Park to the east. The project is being conducted to prevent extreme declines in the caribou populations of the Stevenson and Junction blocks by reducing wolf densities from 1 per 140 sq km to 1 per 700 sq km and to assess the impact of the wolf removal on moose calf survival. No wolf removal will take place in Wells Gray Park or in the Quesnel block, so caribou numbers and calf survival can be compared to those in the removal areas. Wolf numbers will be monitored and additional wolf control may be required over the course of the project if their numbers increase above the target size.
